Re: [Nouveau] Hardware decoding in video playback with Nvidia GT 218 (NVA8)
First of all really thanks for your quick reply! I followed your suggests: -- $ cat /etc/X11/xorg.conf.d/20-nouveau.conf Section "Device" Identifier "Nvidia card" Driver "nouveau" Option "DRI" "3" EndSection After rebooting, I test various ways, by using mpv, with -vo=vdpau -hwdec=vdpau", using mplayer string you suggested in your link: mplayer -vo vdpau -vc ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau,ffh264vdpau,ffodivxvdpau, But without luck... With Option "DRI" "3", I also noticed a worse response during playback, video colors not proper and after a bit it is blocked. I can't close mplayer window, after pressing "q" whole system results crashed and have to hard power off for rebooting again. If you need more details about video file format used to test please let me know, anyway I tried with a 1080p video and 50 FPS, so that it should be a bit lighter to decode and manage by the low budget chip of my card. I also would ask for a question: in your testing experience are you used same GPU of mine GT218 (see details in my previous message) ? Is it known it should be working on hardware video decoding with nouveau drivers? If some other tests or some involved software recompile could be solve this issue, I'm ready to follow your instructions for what are my skills (poor skills! ;) ). Otherwise I'll give up and re-switch to nvidia closed drivers. Thanks again!

Proprietary driver will definitely work better for hwdec than nouveau. Forgetting about any stability/performance issues, there are some reference frame ordering issues in H.264 decoding that were never addressed. This leads to occasional corruption in some videos. FWIW I've mostly tested with mplayer, and I didn't run into problems there. There should be instructions on using mplayer at https://nouveau.freedesktop.org/VideoAcceleration.html. The thing you esp want to avoid is using VDPAU + GL in the same process -- so things like "-vo vdpau" are much more likely to work than "-vo gpu" or "-vo gl". You can try enabling DRI3 -- perhaps something broke in the DRI2 paths. You can add Option "DRI" "3" into the Driver section of the xorg.conf to expose it. It's not on by default because there are some annoying corner cases that some window managers run into with it (KDE as I recall). I'm also not sure why VA-API is corrupted for you, it has worked in the past. But it gets a lot of changes only reviewed by AMD developers, so it can get broken pretty easily with AMD-specific assumptions which don't hold on NVIDIA. I suspect it should be easy to fix by someone who is interested in investigating -- probably a bisect to sort out what broke it, and then revert or get the person who wrote it to fix it.

[Nouveau] Hardware decoding in video playback with Nvidia GT 218 (NVA8)
Hi all, I'm trying to make running hardware acceleration decoding on
my old GeForce 210 (AKA GT-218, or NVA8 / NV-50 Tesla family).
--
02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GT218
[GeForce 210] [10de:0a65] (rev a2)
--
I usually used proprietary nvidia-legacy340.108 driver and it works
quite well even if I noticed some A-V sync (or a bit of frame
dropping) issues during video playback of some videos having 1080p and
60 FPS (h264 encoded). Those issues seem solved by turn off hardware
decoding.
With MPV player and closed nvidia driver I used options:
"-vo=gpu -hwdec=auto"
And it automatically chooses "vdpau" decoding. CPU rests on 5% of load
and so on...
But I read about good if not better performances of some nvidia cards
by using Nouveau open drivers, especially for old GPUs which could
have poorly updated/maintained proprietary driver. So I decided to
switch to open ones.
I'm using Slackware64-15.0 with multilib support.
It runs kernel 5.15.38.
I read on nouveau page about the need of some files extracted from
proprietary driver, a closed firmware for video hardware decoding. On
slackware it is provided by SlackBuilds community:
https://slackbuilds.org/repository/15.0/system/nvidia-firmware/
It populated /lib/firmware/nouveau with variuos files I think related to my GPU:
--
$ file /lib/firmware/nouveau/nva{3_{b,p,v},8}*
/lib/firmware/nouveau/nva3_bsp:data
/lib/firmware/nouveau/nva3_ppp:data
/lib/firmware/nouveau/nva3_vp: data
/lib/firmware/nouveau/nva8_fuc084: symbolic link to nva3_bsp
/lib/firmware/nouveau/nva8_fuc085: symbolic link to nva3_vp
/lib/firmware/nouveau/nva8_fuc086: symbolic link to nva3_ppp
I also enable "nouveau" in /etc/X11/xorg.conf.d/20-nouveau
--
$ cat /etc/X11/xorg.conf.d/20-nouveau.conf
Section "Device"
Identifier "Nvidia card"
Driver "nouveau"
EndSection
--
Here is env-var VDPAU_DRIVER defined to "nouveau"
--
$ grep -v "^#\|^$" /etc/profile.d/vdpau.sh
export VDPAU_LOG=0
export VDPAU_DRIVER="nouveau"
-
On my system are installed:
-
libvdpau-1.4-x86_64-3
libvdpau-compat32-1.4-x86_64-3compat32
--
The second one is related to multilib environment.
